It might be time to look for part t1rfkb1 for your refrigerator and replace that water filter, especially if your water contains chlorine. Chlorine can be a necessary evil. Though on one hand it can kill water-borne diseases, on the other hand it can combine with organic acids that are naturally found in water and create carcinogens, which cause cancer. Not only can chlorine be harmful, it doesn’t taste good, either. Who wants to drink water that tastes like it has been flavored with a hint of bleach? (Which is basically what chlorine is). Remove chlorine from your water and improve both its taste and safety.
